Abstract
Low head loss systems are detailed. The systems may include chambers having low impedance to water flow therethrough and repositionable gates or other valves within the chambers. The valves may direct water as a function of whether an associated heating device is active. At least some gates may incorporate poppet valves or other high-flow by-passes.
Claims1
A valve comprising:
- a. a solid face having a generally circular opening therein and moveable between at least first and second positions;
- and
- b. a poppet assembly comprising:
- i. an elongated stem;
- ii. a generally circular disc attached to the stem and of a size at least that of the opening;
- and
- iii. a coil spring positioned about the stem and in contact with the disc so as to bias the disc to close the opening unless force of fluid impinging on the disc exceeds force provided by the coil spring on the disc.
